G. Rocha et al., Python I, II, and III cosmic microwave background anisotropy measurement constraints on open and flat-A cold dark matter cosmogonies, ASTROPHYS J, 525(1), 1999, pp. 1-9
We use Python I, II, and III cosmic microwave background anisotropy data to
constrain cosmogonies. We account for the Python beamwidth and calibration
uncertainties. We consider open and spatially flat-Lambda cold dark matter
cosmogonies, with nonrelativistic mass density parameter Omega(0) in the r
ange 0.1-1, baryonic mass density parameter Omega(B), in the range (0.005-0
.029) h(-2), and age of the universe t(0) in the range (10-20) Gyr. Margina
lizing over all parameters but Omega(0), the combined Python data favor an
open (spatially flat-Lambda) model with Omega(0) similar or equal to 0.2 (0
.1). At the 2 sigma confidence level, model normalizations deduced from the
combined Python data are mostly consistent with those drawn from the DMR,
UCSB South Pole 1994, ARGO, MAX 4 and 5, White Dish, and SuZIE data sets.
